System and method for enhanced video selection and categorization using metadata

ABSTRACT

Systems and methods for presenting video asset information to a viewer to assist the view in selecting a video asset for viewing is described. The video assets can be available from a plurality of different video asset sources, such as VOD (video on demand), PVR (personal video recorders) and broadcast (including over the air, cable, and satellite). Images from the video assets are displayed in a uniform manner, along with information about the video assets. The information includes data in a metadata category, wherein metadata can be received from the video asset, external sources, or manually input by a user. The view can select one of the video assets for viewing, but also can navigate using metadata categories such as genre, actors, director, and the like. This allows a much easier and natural navigating and selection process for viewers.

RELATED APPLICATION

This application is a continuation-in-part application of U.S. patent application Ser. Nos. 11/081,009 and 11/080,389, filed on Mar. 15, 2005, which claim the benefit of U.S. Provisional Application No. 60/560,146 filed on Apr. 7, 2004, each of which is incorporated herein by reference in their entireties.

FIELD OF THE INVENTION

This invention is directed towards multi-channel video environments, and more particularly towards systems and methods for navigating through video assets that are broadcasted and available on a server for play out.

BACKGROUND

With the introduction of multi-channel video, Electronic Program Guides (EPGs) were developed to assist consumers with navigating the ‘500 Channel’ universe. These EPGs allowed features such as grouping of similarly themed programming, look ahead (and often marking for recording), navigating by Favorite Channels, etc. EPGs typically give access to currently showing, and shortly upcoming linear television programming.

With the rise of Video-On-Demand (VOD), EPGs have needed to toggle between VOD offerings and linear offerings. This has been somewhat of a compromise because prerecorded material offered through a VOD service cannot be selected directly through the EPG listings for linear channels. In addition, the VOD selection mechanisms are often modeled as hierarchical menu selection structures. With the steady increase of content available through VOD servers, this makes it increasingly difficult for consumers to navigate all available content.

Personal Video Recorders (PVRs) have had a similar effect: programming available on a PVR is typically presented separate from the linear programming and even from the programming available on VOD. Thus, consumers effectively “toggle” between linear programming, VOD programming, and PVR programming to browse all available programming.

Accordingly, there is a need to be able to tie these technologies together to enable the consumer to browse and search available programming content using metadata values in a consistent manner, and to represent the metadata in an intuitive way so that it is easy to relate them to the programming content.

SUMMARY

Advantageously, technologies have been developed to enable topically linked searches across multiple databases, meta data descriptors have been developed to more fully capture characteristics of such content as well as sub-sections of such content, and technologies have been developed where video scenes can have part of the screen with hot links to meta data objects.

Certain embodiments of the present invention relates to a system for gathering video asset information to assist a user in selecting one or more video asset for viewing, where the one or more video assets are available from a plurality of different video asset sources. The system includes a metadata retrieval component that receives customized metadata information associated with the one or more video assets from at least one external sources or from a content portion of the one or more video assets; a means for grouping the one or more video assets according to at least one metadata category, the metadata category being a function of the received customized metadata information; and a means for formatting the grouped one or more video assets for presentation to the user so that the user can select and view the one or more video assets irrespective of the video asset source.

Certain embodiments of the present invention also relates to a device for gathering video asset information to assist a user in selecting one or more video asset for viewing, where the one or more video assets are available from a plurality of different video asset sources. The device includes a metadata retrieval component that receives customized metadata information associated with the one or more video assets from at least one external sources or from a content portion of the one or more video assets; a means for grouping the one or more video assets according to at least one metadata category, the metadata category being a function of the received customized metadata information; and a means for formatting the grouped one or more video assets for presentation to the user so that the user can select and view the one or more video assets irrespective of the video asset source.

Certain embodiments of the present invention also relates to a method for gathering video asset information to assist a user in selecting a video asset for viewing, where one or more video assets are available from a plurality of different video asset sources. The method includes receiving customized metadata information associated with the one or more video assets from at least one external sources or from a content portion of the one or more video assets; grouping the one or more video assets according to at least one metadata category, the metadata category being a function of the received customized metadata information; and formatting the grouped one or more video assets for presentation to the user so that the user can select and view video assets irrespective of the video asset source.

Certain embodiments of the present invention also relates to a computer program product residing on a computer readable medium, the computer program product having instructions for causing a computer to receive customized metadata information associated with the one or more video assets from at least one external sources or from a content portion of the one or more video assets; group the one or more video assets according to at least one metadata category, the metadata category being a function of the received customized metadata information; and format the grouped one or more video assets for presentation to the user so that the user can select and view video assets irrespective of the video asset source.

DETAILED DESCRIPTION

A schematic overview of a prior art VOD system is shown in FIG. 1. The system consists of a VOD Back-End component 20 (residing in a cable head-end) and a Receiver Device 22 and Display Device 24 at the consumer's home. The Receiver Device 22 may be a digital set-top box, or any other receiving device including computers or media processors. The Display Device 24 can be a TV set, or any other display or monitoring system. Further, the Receiver device 22 and Display Device 24 may also be combined into one physical device, e.g. a “Digital Cable Ready” TV set, or computer/media center. The backend component 20 may comprise several modules, such as one or more VOD Storage servers 26 (used to store the programming that is available to the consumers), one or more VOD Pumps 28 (used to play out the programming as requested by the various consumers that are actually using the system at any point in time), a Subscriber Management & Billing module 30 (used to interface with the subscriber database, and for authentication and billing services), a Management & Control module 32 (used to overall manage the system, assets, and resources), and a Content Ingest module 34 (used to load new programming content onto the system).

In a typical usage scenario, the consumer 25 would “toggle” to VOD (e.g., by pressing a special button on their Received Device remote control). This causes the Receiver Device to send an initiation signal to the VOD Back-End over the Command & Control channel, and then typically to tune to a VOD channel, which gives the consumer a menu of available VOD assets from which to select. This menu is typically implemented as a hierarchical text-oriented menu system, where the user can select sub-menus and order VOD assets with key presses from their remote control. This is illustrated in the menu chain 36 of FIG. 2, where the consumer selects “Movies” from the main menu, then selects “Action Movies” from Sub Menu 1, then selects “Hannibal” from Sub Menu 2, then confirms the transaction to buy Hannibal at Sub Menu 3. Once all this is done, the VOD Back-End system 20 will allocate Hannibal in the VOD Storage system 26, allocate an available VOD Pump 28, and instruct the VOD Pump 28 to start playing out Hannibal on an available bandwidth slot (frequency) in the network. The Receiver Device 22 will then tune itself to this slot, and start to display the asset on the Display Device 24 so that the consumer 25 can view the asset. During the viewing process, the consumer 25 typically has the ability to Pause, Rewind, and Fast-Forward the movie by pressing buttons on his or her remote control. For example, when the consumer 25 presses the Pause button, the Receiver Device will send a Pause message (via Command & Control channel 27) to the VOD Back-End 20 to pause the movie. A VOD session can end because the movie viewing has ended, or because the consumer 25 decided to terminate the session by pressing one or more special buttons on the remote control, in both cases the system will go back to regular television viewing mode.

Current interfaces and systems for searching and browsing VOD assets are often problematic and not always effective. The systems are often implemented as hierarchical menu systems, are not very flexible, and not very intuitive. As a result, it is not always possible for a consumer to find a VOD asset for viewing unless they know the exact title and properties of the asset they are looking for. This problem gets even worse if the number of available VOD assets on VOD systems increases.

The present invention provides a new paradigm for browsing and searching video assets available on VOD and from other sources. The present invention takes advantage of metadata for the assets (e.g. “lead actor”, “director”, “year of release”, etc.), and in one embodiment uses it to enable the consumer search for certain assets (e.g. “find all assets starring or associated with Clint Eastwood”). It also provides powerful associative search capabilities (e.g. “I like movie X, so find me all assets that have the same lead actor”). Also, the present invention presents the consumer with an intuitive user interface (pictures instead of text) that can be easily navigated with traditional remote controls (no need for keyboards).

Further features of the present invention are described in U.S. patent application Ser. No. 11/080,389 filed on Mar. 15, 2005 and entitled METHOD AND SYSTEM FOR DISPLAY GUIDE FOR VIDEO SELECTION, which is incorporated herein by reference.

An illustrative implementation of the present invention in a digital cable system will now be described, first in terms of functionality to the consumer, then in terms of implementation in a cable system or environment.

Consider a consumer 25 in a digital cable system, who has access to VOD service, and also has a digital receiver device 22 that includes PVR (personal video recorder) service. To start off with, the consumer will be watching a movie, so his display may show full screen video as depicted in FIG. 3. At any point in time during the movie, the consumer can initiate (by pressing a specific button on his remote control) an interactive information banner 38 to be displayed on his display, as illustrated in FIG. 4. In this example, the banner 38 contains the channel logo 40 on the left, and some textual description 42 of the current movie to the right. The description contains a number of “linked fields” 44, which are marked by some visual effect (in this example they are underlined). The fields 44 represent associative searches for assets with the same attribute (so the “Will Smith” field represents all assets that feature Will Smith as an actor).

The consumer can navigate between the linked field with buttons on the remote control (current selection may be indicated by highlighting it), and then activate one of the links by pressing yet another button on the remote control. For this example, assume the consumer activates the “Will Smith” field. This will lead into a metadata browsing screen (in this case for “Will Smith”) as illustrated in FIG. 5. This screen provides the results of a search for all assets that share the same metadata (in this case “Starring Will Smith”). In this example, the screen holds nine assets, and each asset is shown as a combination of a still picture 46 (clipped from the asset or from an alternate source) and the title 48 of the asset along with other information such as the release year 50 of the asset and a symbol 52 indicating where the asset is available. Possible values for symbol 52 are: VOD (available in the VOD archive) 52 a, Showing (currently showing) 52 b, PVR (available on PVR) 52 c, and Guide (shows up in the Guide, so available in the future) 52 d. Other possible values for this symbol 52, as well as alternative sources of the assets, such as DVD jukeboxes, tape jukeboxes, and media delivered by IP networks (including Ethernet, fiber, carrier current, wireless, etc.), are also within the scope of the invention.

Typically, one of the assets is highlighted 54 (indicating current selection, in this case the “Wild Wild West” asset). Other methods of drawing attention to the presently selected asset, including but not limited to blinking, ghosting, color changes, alternate borders, etc. are within the scope of the present invention. The consumer can change the current selection using keys on the remote control. In case there are more assets than fit on the screen, the consumer can move to previous and next pages similarly using remote control buttons. The consumer can activate the currently selected asset by pressing a specific button on the remote control. This will take the consumer to a preview/trailer session for the selected asset. For this example, assume the consumer has selected “I Robot”, the resulting preview/trailer screen is illustrated in FIG. 6. The preview can be any length theatrical preview, during the preview the consumer has the ability to purchase for viewing the VOD asset by pressing a button on the remote control (in this case the “Select” button). The consumer also has the option of viewing the purchased asset immediately, or potentially selecting a later time to view the VOD asset, allowing for example a parent to make a purchase with password protected purchase option, for the children to view later in the evening. Further, if the VOD asset may be downloaded to a PVR, thereby allowing the consumer to then view the asset from the PVR. The consumer may also pause, fast forward, rewind the contents of the preview. Also, the consumer may press the remote control button for the interactive information banner, which will result in the interactive banner 42 as illustrated in FIG. 7. As discussed before, the consumer may now navigate the links in the banner, etc.

The preview/trailer may look slightly different for assets that are available through other means than VOD. FIG. 8 shows one embodiment of the preview screen when a currently showing asset is selected (in this example Ali), FIG. 9 shows one embodiment of the preview screen when an asset is selected that is available on PVR (in this example Enemy of the State), FIG. 10 shows one embodiment of the preview screen when an asset is selected that is available in the Guide (in this example Men In Black). The application logic for this illustrative embodiment is further shown and summarized in the process flow 56 in FIG. 11. Depending on the type of asset, different actions are taken that are appropriate for that asset, as previously discussed with FIGS. 6 and 8-10.

An implementation of this illustrative embodiment in a cable head end will now be discussed. This implementation is illustrated in FIG. 12. As shown, certain embodiments includes a VOD storage component 26, a VOD pump component 28, a Subscriber Management & Billing component 30, Management & Control component 32, Content Ingest component 34, Clip/Still Store component 58, Search Metadata Database component 64, Asset Availability Database component 70 and Search Application Server component 78 which plays out video assets, receives commands and control, and sends commands and controls to Receiver Device 22. The Receiver Device 22, which includes a Search Application 76, interacts with a Display Device 24 to allow Consumer 25 to view and/or select any desired video assets.

The Clip/Still Store component 58 is illustrated in greater detail in FIG. 13. The Clip/Store component 58 stores and manages previews, trailers, and still pictures that are associated with assets that are available to the consumer. The Clip/Store component 58 provides a unified database of various trailers and stills that are associated with an asset. The Clip/Store component 58 gets its information from various sources. First, whenever new content enters the VOD system, the Content Ingest module 34 notifies the Clip/Still Store component 58. If the new content already has associated clips/stills for preview, the Clip/Still Store component 58 simple administers and stores it for later use. If no clips/stills are associated with it, the Clip/Still Store component 58 may automatically extract appropriate clips/stills from it. Information supplied with the asset or obtained separately may provide one or more appropriate time/frame references for clips or stills from that asset. Second, the Clip/Still Store 58 may be connected to a variety of internal and external sources of clips and stills 60. Examples of these sources are online Internet Movie Databases (www.imdb.com), or libraries of VOD and other content. Third, the Clip/Still Store 58 may have a user interface 62 that allows operators to manually extract clips and stills from an asset.

Another system component is the Search Metadata Database (DB) component 64, FIG. 12, as detailed in FIG. 14. This component 64 provides unified metadata for all assets that are available to the consumer. It also provides interfaces to search for assets based on metadata values. The Search Metadata Database component 64 gets its information from various sources. Component 64 can be a single component or made up of numerous individual components such as a metadata retrieval component, a metadata sharing component, a metadata listing component, a interface component to allow interaction with the user, a metadata ranking component, and the like as will be readily apparent to one of ordinary skill in the art in light of the descriptions contained herein.

In one embodiment, new content entering the VOD system will typically come with metadata (for example, see the Cablelabs Metadata Specification and the like). Such metadata that typically comes with the video asset will be referred to as a “native metadata” and all other metadata obtained in a different way will be referred to as a “customized metadata.” The Content Ingest module 58 will notify the Search Metadata Database 64, which then administers and stores the native metadata. For example, new content may be a newly released movie Bad Boys II, starring Will Smith. The native metadata may contain the following information:

Title: Bad Boys II;

Director: Michael Bay;

Stars: Will Smith, Martin Lawrence, Jordi Molla

Genre: Action/Comedy/Crime/Thriller

Plot: Two narcotics cops investigate the ecstasy trafficking in Florida.

Alternatively, the Search Metadata Database 64 is connected to a variety of internal and external customized metadata sources 66. These can be public sources (such as IMDB described below), or libraries of VOD or other content. For example, customized metadata for Bad Boys II shown above can be alternatively downloaded from IMDB, which may contain additional information as shown below.

Title: Bad Boys II;

Director: Michael Bay;

Stars: Will Smith, Martin Lawrence, Jordi Molla, Gabrielle Union, Peter Stormare

Genre: Action/Comedy/Crime/Thriller/Sequel

Plot: Narcotics cops Mike Lowrey (Smith) and Marcus Bennett (Lawrence) head up a task force investigating the flow of ecstasy into Miami. Their search leads to a dangerous kingpin, whose plan to control the city's drug traffic has touched off an underground war. Meanwhile, things get sexy between Mike and Syd (Union), Marcus's sister.

In yet another alternative, the Search Metadata Database 64 may have a system 68 for automatically extracting customized metadata from the content. Some examples of this include inspecting closed captioning information, image analysis for finding words for the opening and/or closing credits, comparison and matching to databases of actors and directors, etc. and any combination thereof. In certain embodiments, the present invention may use a combination of scanning of closed captioning data, combined with pattern recognition software to establish the genre of a movie. For example, the closed caption and pattern recognition software may establish that many exotic cars appear in the movie. Hence, “exotic cars” may be added to the metadata. Also there may be scene detection algorithms to locate the opening and closing credits of a movie, and then the use of character recognition algorithms to determine actors and directors automatically. For example, opening/closing credits may be searched to determine actors Gabrielle Union, Peter Stormare, Theresa Randle, Joe Pantoliano, Michael Shannon, John Seda, and the like appear in the movie. Also, audio (music) may be analyzed to determine genre of a movie, to recognize specific movies, or to determine the artist performing the soundtrack. For example, display guide may already contain in the current library “I Love You” by Justin Timberlake as one available music source. System 68 may compare the music being played in the movie with the available music sources and determine that the soundtrack of Bad Boys II contain “I Love You” by Justin Timberlake. The display guide may be updated to reflect this fact. Furthermore, voice recognition systems may be used to determine actors.

The Search Metadata Database 64 may also receive customized metadata from a user through a user interface 62 whereby consumers can attach customized metadata to content. Examples of interface 62 include, but are not limited to, a general-purpose computer or a cable set-top box having software and hardware that can receive input from one or more input devices such as a remote control. In certain embodiments, an operator may be interested in exotic cars and car chase scenes of a movie. In that case, the operator may utilize the user interface 62 to attach customized metadata “exotic cars” and “car chase” to the video asset. In other embodiments, an operator may be interested in cool guys having little to no hair. In that case, the operator may utilize user interface 62 to attach customized metadata “cool bald guys” to the video asset.

In certain embodiments, one or more of the information sources described above may be combined. For example, after an operator has attached customized metadata “exotic cars” to Bad Boys II, Search Metadata Database 64 may automatically perform a search to determine if metadata “exotic cars” is associated as a native metadata with other video assets. If not, Search Metadata Database 64 may search any of the external or internal sources, such as IMDB, for customized metadata or other textual descriptions having “exotic cars.” If customized metadata “exotic cars” is not found, then system 69 may automatically search the content in the close captions, images, credits, and the like to search whether customized metadata “exotic cars” can be attached to the particular content. Operator may at any time have the option of adding metadata, e.g., “exotic cars,” (or removing if any of the above examples generated an incorrect metadata “exotic cars”) using interface 62.

In certain embodiments, the customized metadata generated by one user/consumer may be shared with other users/consumers. For example, customized metadata generated by a first consumer may be embedded into the appropriate video assets. When a second consumer receives such video assets, the embedded customized metadata may be displayed to the consumer. To the second consumer, the embedded customized metadata may appear similar to a native metadata.

In other embodiments, native metadata and/or customized metadata may be ranked in order of popularity among multiple consumers. A ranking component (not shown) included in the Search Metadata DB component may rank the popularity of native metadata and/or customized metadata by keeping track of the number of times video assets were searched according to the particular customized metadata. For example, if video assets were searched for those having customized metadata “exotic cars” 100 times but only two times for “cool bald guys,” a list of customized metadata may be generated by the ranking component which lists customized metadata “exotic cars” in a higher rank than “cool bald guys.” A consumer may then browse through this list of customized metadata, select the desired customized metadata, and search video assets according to the selected customized metadata.

Another component is the Asset Availability Database 70 in FIG. 12, as detailed in FIG. 15. This database 70 keeps track of which assets are available to the consumer at any point in time. It gets its information from a variety of sources. First, whenever new content enters the VOD system, the Content Ingest module 34 will notify the Asset Availability Database 70 to record and administer the presence of the asset (or delete it if the asset has been removed from the VOD system). Second, the Asset Availability Database 70 is connected to an electronic source of Program Information 72 (this information is typically supplied to cable operators to populate the Electronic Program Guides in the digital set-top boxes, an example of a supplier of electronic program information in the US is Tribune Data Services). The Asset Availability Database 70 uses this information to keep track of which assets/programs are available for viewing or recording on the various networks in the coming weeks. Third, the Asset Availability Database 70 periodically collects data from all digital receivers 74 that have PVR capability, this information specifies which assets each individual receiver has currently stored and available on its local hard disk drive or other storage medium. This information is typically collected in the background, to not disrupt cable system behavior (e.g. at night). The Asset Availability Database 70 normalizes all this data, and can generate a list of all assets that are available to a specific digital receiver 74 according to the following formula:

Assets_available_to_receiver = IF (receiver_has_PVR) THEN (assets_available_on_VOD + assets_present_in_program_information + assets_on_PVR) ELSE (assets_available_on_VOD + assets_present_in_program_information) END

Another component of the system is the Search Application 76, FIG. 12. This application resides in the Receiver Device 22 at the consumer's premise. It can be an embedded application, a downloadable application, or a built-in feature of another Receiver Device application (such as the Electronic Program Guide). The Search Application 76 has two major functions. First, whenever the consumer initiates enhanced search mode, it will set up a connection with the Search Application Server 78 in the back-end, and handle the user interface to the consumer (according to flow chart in FIG. 11), it will request all metadata, stills, and video play out functions from the Search Application Server 78. Second, in case the Receiver Device 22 includes a PVR, it will periodically send a list of assets available on PVR back to the Asset Availability Database 70 in the back-end. A final component of the system is the Search Application Server 78. This server acts as the engine of the application, whenever a consumer initiates enhanced search mode, the Search Application Server 78 receives a request to open a search session, and inside that session it will continue to get requests for metadata, stills, or video play outs. The Search Application Server 78 in turn will interact with the Clip/Still Store 58 to retrieve clips or stills, to the Search Metadata Database 64 to retrieve metadata, the Asset Availability Database 70 to find lists of available assets, and the VOD Storage and/or VOD Pump components to play out trailers and/or VOD assets.

One of the advantages of the present invention is that the required user input from the consumer can easily be mapped on an existing remote control device, thus avoiding the need for more complex input devices such as remote keyboards. In other words, it is straightforward to map all required user inputs on existing keys on existing remote controls. A sample mapping on remote control 80 keys is shown in FIG. 16 (note: this is only one of the possible mappings, also note that only the keys associated with this application are shown, in reality there will be plenty of other keys as well).

The implementation describes only one possible embodiment of the present invention. It should be clear to anyone skilled in the art that the invention can also be implemented in alternative embodiments and implementations. Without attempting to be comprehensive, alternative embodiments will now be disclosed

One enhancement to the previously described embodiment is to add personalization to the system. This would further refine the user interface to the personal preferences or history of the consumer. For example if a consumer is presented with all Will Smith movies, the system may take into account that the consumer is interested in Sci-Fi movies, and it would present the Will Smith movies from the Sci-Fi category first. Also the stills and clips could be personalized. For example different aspects of the movie may be highlighted to appeal to different personal profiles (the movie “Pearl Harbor” may be presented as a love story to someone interested in romantic movies, and as a war movie for someone interested in war movies, this would result in different clips and stills to be shown to represent the same movie). Moreover, any of the metadata found by Search Metadata Database 64 may be utilized for further customization. For example, all content may be categorized by metadata “exotic cars” and all content having metadata “exotic cars” may be presented to the user via a metadata browsing screen (similar to that shown in FIG. 5).

Such a feature could be implemented by adding a Personalization Server 82 to the back-end 20 infrastructure. This Personalization Server 82 is illustrated in FIG. 17. The purpose of this server 82 is to maintain personal profile information for each potential user of the system (consumer). The personalization server 82 builds and maintains these profiles from various inputs. First, it may get subscriber information from the cable operator's subscriber database 84. This information may include some basic demographics (gender), past VOD buying behavior, etc. Second, it may get information from other (external) demographic databases 86 with more detailed demographics (income, etc.). Examples of such database providers in the US include Axiom and InfoUSA. Third, it may collect viewing behavior from the various client devices 74. For example, client device 74 may be a device that allows a certain member of the family, for example a son who is interested in “exotic cars,” is using the display guide. Client devices 74 may also include information on what programs are watched most frequently by that particular family member. The Personalization Database 82 will normalize all this information, and then apply it to the Clips/Stills collection 58 that is available, and to the metadata collection 64 that is available, and it will select the most appropriate Clips/Stills for a given consumer and/or customize the descriptive text or metadata towards a specific consumer.

FIGS. 18A-18D show example screen shots according to an embodiment of the invention. The images of television shows in these figures (and the subsequent figures) are for exemplary purposes only, and no claim is made to any rights for the shows displayed. All trademark, trade name, publicity rights and copyrights for the exemplary shows are the property of their respective owners. FIG. 18A shows a display for video assets which for this example are broadcast shows arranged by viewing time. The broadcast shows are displayed with a still or moving image of the broadcast show, also a network logo is included as part of the image, superimposed or combined with the image. A user can use a remote control to highlight a selected broadcast show for viewing or for interactively obtaining further information about the highlighted broadcast show. The user is not required to deal with channels or other underlying details of video asset delivery, but can simply navigate by more familiar terms, in this case by network. Further, the user may selectively add or remove entities (and arrange the order of the displayed networks) from the display, to personalize the display for that user. FIGS. 18B-D show different displays based on selected time slots as shown on the bottom of the image.

FIG. 19A shows another screen shot from this embodiment. In this case the user is viewing video assets for a particular show, where the video assets are available from a source such as video on demand, library, or other delivery service. The user can easily select a certain episode for viewing, or to obtain further information, for example as shown in FIG. 19B. As previously described, a user can have the ability to search for other video assets based on information and meta-data categories that are displayed with the image.

FIG. 20 shows another screen shot from this embodiment wherein a user may navigate using tabs positioned along a top of the display, and select different categories of video assets. In the present example, the user has selected a category of “My Favorites”, and is shown a selection of video assets for viewing. As shown in this figure, the video assets are available from a wide variety of sources, including DVD, broadcast, and pay per view broadcast. The user is able to select a video asset (through highlighting interactivity with a remote, or otherwise) for viewing from a vast number of video asset sources. Further, the user can navigate to other similar video assets (based on the meta-data categories) using the video assets presently listed in this favorite category.

FIG. 21 shows another screen shot from this embodiment, which shows the ability to provide advertisements, interactive shopping experiences or special offers to users. As shown in the image, selection of advertising assets are presented to the user, to allow the user to interact by selection and thereby view and/or receive special offers from such advertisers. A visual indication on an image can alert the user to a special offer or interactive opportunity for certain advertisements. The user has the ability to use meta-data categories to search for other advertisers or suppliers of goods and services, for example to search for other amusements parks based on a meta-data category for one image and advertisement for an amusement park.

Another implementation variation is to selectively use still pictures instead of video previews/trailers. This has a number of advantages: first still pictures may be more readily available than previews/trailers, especially for content that is available through other means than VOD (e.g., content that shows up in the Guide for two weeks from now), second this could limit the bandwidth consumption (still pictures take considerably less bandwidth and storage than moving video). Bandwidth use can be further limited by sending the still pictures in so-called broadcast carrousels and to have them stored at each client device 74 when needed (as opposite to sending them to the client device on request when needed). Broadcast carousels are a well known bandwidth saving technique in the digital video industry (an example is the DSM-CC Data Carrousel). It is within the scope of the invention to modify the system in such a way that it detects shortage of bandwidth, and then switches over to more bandwidth friendly techniques (stills), and switch back to using motion video when bandwidth is more available again.

Another implementation variation is to “auto cue” additional previews/trailers after the consumer is finished watching a preview. In other words: if a user previews the “Ali” preview and does not decide to buy the movie, or exits the application, the system may automatically start playing the next relevant preview (instead of going back to the Browsing Screen). It is possible to enhance the system in such a way as to effectively create an interactive movie barker channel (continuously playing relevant trailers).

Another implementation variation is to load trailers to hard disks of PVR-enabled Receiver Devices. This would allow these trailers to be played out from local hard disk (even if they refer to a movie asset that is available on VOD, or as linear programming). The trailers could be downloaded when bandwidth is available (e.g., at night), and this would also make the system much more bandwidth efficient.

Another implementation variation is to use the system to represent assets from additional sources (in addition to, or instead of, VOD and PVR and linear programming). Examples would include: assets that are available via Broadband IP networks, assets that are available on DVD or DVD-Recorder, assets that are available via Digital Terrestrial networks, assets that are available via Direct-To-Home (DTH) satellite, assets that are available on Near-Video-On-Demand (NVOD) channels, assets that are available via Subscription-Video-On-Demand (SVOD), etc. Further, assets can be downloaded from a network or path that does not provide enough bandwidth for real-time viewing. The asset may be downloaded to the PVR, and the consumer can be alerted when the asset is fully downloaded, or alternatively, when enough of the asset is downloaded to allow the consumer to begin viewing from the PVR while downloading continues in parallel (in effect using the PVR as a buffering system).

Another implementation variation is to change the User Interface Look & Feel to accommodate different flavors of interfaces. The system may easily be modified to provide different views or representations of the video (either as still picture or as moving video) in combination with a representation of metadata. Also different input devices can easily be supported (more advanced remote controls, keyboards, media control center consoles, etc.).

Another implementation variation is to give viewers more control/preview capabilities by presenting them with a screen that shows them the various parts of the movie that they are (about to) see. This screen can look very similar to the metadata browsing screen (or the scene selection screen typically used in many DVD titles today), and allow the viewer to get a better understanding of the flow of the movie, and give the viewer control to navigate the movie in a more user friendly manner.

Another implementation variation is to use moving video in the metadata browsing screen (instead of still pictures). The various assets can be shown as moving pictures, and only the audio of the currently selected asset would be rendered. In order to make implementation easier, the moving pictures can be low-quality, or even animated still pictures.

Although the invention has been shown and described with respect to illustrative embodiments thereof, various other changes, omissions and additions in the form and detail thereof may be made therein without departing from the spirit and scope of the invention.
